PROTECTIVE EDGES FOR SKI-RUNNERS 2 Sheets-Sheet 2 FIG. 8

INVENTOR. filvro 1408. nvaew United States Patent 3,134,604 PROTECTIVE EDGES FOR SKI-RUNNERS Anton Aublinger, 101 Mutters, Tirol, Austria Filed June 13, 1961. Ser. No. 116,783 3 Claims. (CI. 280-11.13)

The invention relates to a protective edge for skirunners, and to ski-runners provided with such protective edges.

It is an object of the invention to provide a protective edge for ski-runners which has the effect that a skirunner provided therewith cuts well into the surface of the snow even when the surface layer of this snow is well hardened, without however hampering the running of the ski.

With this and other objects in view which will become apparent later from this specification and the accompanying drawing I provide a ski-runner comprising protective edges fixed along its underside and having over at least part of the total length of said runner an outer substantially sinusoidal wave form contour throughout the thickness of the protective edge.

This wave form contour preferably, but not necessarily, protrudes laterally at least partly beyond the side face of the ski-runner. Alternatively it may end substantially flush with the said side face, and the underside of the skirunner is then chamfered adjacent said protective edges.

With ski-runners having a metal-lining on their underside the protective edges may be integral with said lining.

The protective edge may extend in one piece along the full length of the ski-runner on each side of it, or may be composed of separate sections.

These and other objects and features of my said invention will be clearly understood from the following description of some embodiments thereof given merely by way of example with reference to the accompanying drawings, in which:

FIG. 1 is a plan view from underneath of a ski-runner having wavy contour protective edges,

FIG. 2 is a detail of FIG. 1 on a larger scale,

FIG. 3 is a cross section of FIG. 2,

FIG. 4 shows an individual protective edge section in plan view, and

FIG. 5 shows the same in side elevation.

FIG. 6 shows a plan view from underneath on a larger scale part of a ski-runner with a special manner of mounting protective edges according to the invention.

FIG. 7 is a cross section of FIG. 6.

FIG. 8 is a plan view from underneath on a larger scale of a part of a metal-clad ski-runner having protective edges according to the invention, and

FIG. 9 is a cross section of FIG. 8.

In the embodiment according to FIGS. 1 to 5 the protective edges 1 consist of individual sections, the outer contours 2 of which are shaped according to an approximately sinusoidal wavy line. As shown in FIGS. 2 and 3 the protective edges 1 are mounted in such a manner, that their outer wavy margins protrude beyond the side faces 3 of the ski-runner.

According to FIGS. 2 and 3 the wavy outer contours of the protective edges protrude slightly beyond the side faces of the ski-runner. This is however not indispensible. For example, alternatively a mounting could be made in accordance with FIGS. 6 and 7, in which the crests of the convex outer arcs of the wavy protective edges 19 do not protrude beyond the side faces of the ski-runner 39. Preferably in this case an inward chamfer 49 may be provided on the ski-runner 39 just above the protective edge 19.

7 3,134,604 Patented May 26, 1964 In the embodiments described herein-above the protective edges were formed by separate edge strips. FIGS. 8 and 9 show an embodiment of a ski-runner having metal layers (metal-lined ski-runner) wherein separate edge strips are dispensed with, while the outer contours 22 of the lower metal lining 52 deviate according to the invention from the side faces 32 of the ski-runner. In this case the lateral portions of the metal lining 52 itself form the protective edges.

It is irrevelant, whether the protective edges are composed of several discrete sections or are in one piece for the whole length of the ski runner. It is likewise irrevelant, how the edges are fixed to the ski runners, whether by screwing, riveting, glueing, casting-in, etc.

In short, while I have described herein what may be considered typical and particularly advantageous embodiments of my said invention, I Wish it to be understood that I do not limit myself to the particular details and dimensions shown and illustrated; for obvious modifications will occur to a person skilled in the art.

What I claim as my invention and desire to secure by Letters Patent, is:

1. A ski runner having a substantially flat running face and side faces normal to the plane of said running face, said ski runner comprising protective edgings secured along the running face and extending over at least the major portion of the length of the runner, said edging having side faces of a shallow, substantially sinusoidal wave form, chamfered edge portions between said side faces and said running face, the wave form contours of said edgings being substantially flush with said side faces, a groove of substantially triangular cross section being provided between said chamfered edge portions and the upper side of said edgings.

2. A ski runner having a width identical over the major portion of the length of the runner and comprising protective edgings secured to the runner at the running side thereof and extending over at least the major portion of the length of the runner, said edgings having inner side faces of rectilinear form flatly adjacent to the ski runnerand laterally outer side faces of substantially sinusoidal wave form, disposed normal to the plane of the runner, the contours of said outer side faces forming a plurality of wave peaks and wave troughs and defining angles of at most 30 with a longitudinal direction of the runner.

3. A ski runner having a width identical over the major portion of the length of the runner and a substantially flat running face, side faces normal to the plane of said running face, and a metal lining on the running side of the runner, said metal lining protruding beyond the side faces of the ski runner and having laterally outer side faces of substantially sinusoidal wave form disposed normal to the plane of the runner, the contours of said side faces forming a plurality of wave peaks and wave troughs and defining angles of at most 30 with a longitudinal direction of the runner.
